Application May 8, 1939, Serial No. 272,481 Claims. (ol. 34-99) Thisinvention relates to electric motor operated hair driers of the typeused in hair emporiums, so-called beauty parlors and the like. Theparticular embodiment under advisement has reference in particular to aportable pedestal-style high-boy structure wherein the motor driven fanis on the base at a point remote from the head accommodating andreceiving drier hood.

In accordance with the principles followed in constructing hair driersof the aforementioned types, a perpendicular hollow standard rises froma roller equipped base or stand, the standard being provided at itsupper end with an adjustable hood and the air blower or fan beingdesigned to deliver the flowing air into the conduit-forming standard.In an effort to place the blower as far away from the hood as isreasonably possible, structures of this type are given to development ofseemingly unbearable noises. Unless the motor is cushioned and properlymounted and the blower constructed in accordance with the newerprinciples of this invention, an incessant noise tantamount to anerve-wracking roar is created. So the unwilling victim, the customersubjected to this deplorable condition, must undergo untold punishment.

The trade in general has long recognized this unwanted condition. Infact, it would appear that the so-called pedestal-style noisegeneratinghair driers are perhaps destined to abandonment unless the roar issubdued and the machine constructed to satisfactorily serve and placatefeminine customers. ered the need for a revision of present day hairdriers of the type under consideration, but we have evolved and actuallyproduced a unique construction and arrangement which aptly fulfills therequirements of the trade and minimizes vibration and attendant noiseand roar to the extent that one has to listen intently in order todetect the presence of our now substantially silent motor driven blower.

Briefly, in reducing to practice the preferred embodiment of our ideas,we have perfected a motor and blower assembly adequately fitted toaccomplish our purposes. With this assembly is associated a telescopicstandard forming the air delivery conduit, the sections of this beinginsulated to cut down vibration and noise so that the adopted featurescollectively serve their proportionate share in providing an-acceptablesubstantially noiseless hair drier.

Other somewhat secondary and subordinate Not only have we discovfeatureswill become more readily apparent from the following description and theaccompanying illustrative drawings.

In the drawings, wherein the preferred embodiment is disclosed and likereference characters are utilized to designate corresponding detailsthroughout the views:

Figure 1 is a side elevational view of a hair drier constructed inaccordance with the principles of our invention.

Figure 2 is a vertical central sectional view through the assembly seenin Figure 1.

Figures 3, 4, 5,-and 6 are detail sectional views taken on the lines3-4, 44, 55, and 66, respectively of Figure 2.

Figure 7 is a view of the wiring diagram of the multiple unit electricheater means.

Figure 8 is a fragmentary top plan view of the adjusting and retentionmeans for the tiltable or adjustable hood.

Figure 9 is an enlarged fragmentary detail sectional view on the line9-9 of Figure 1.

Referring now to the drawings by distinguishing reference numerals, thebase or stand 10 comprises a plurality of downwardly diverging legs llhaving at their lower ends rollers or casters 12 to facilitate mobilityof the structure as a Whole. The horizontal frame bars I3 carried by thelower portions of the four legs have a pair of parallel cross-bars I4therebetween. Saddled in the space between the cross-bars I4 is theinsulated housing or casing l5 of the blower unit IS. The marginalperipheral rim is suspended between the bars M as brought out toadvantage in Figure 2. The discharge neck I! is in communication withand adjoined to the lower stationary section l8 of the tubular standard.It is highly important to note that the vertically parallel side wallsof the fan housing are provided with opposed openings l9 and 20 (seeFigure 5). The smaller opening l9 may be described as an air intake. Thelarger opening 20 is an air vent and the two openings collectivelyreduce air roar at this point to a minimum. Vibration is cut down bymounting the electric motor (of any suitable type) 2| in a properlycushioned harness. That is to say, the motor is surrounded by rubber orequivalent cushioning means 22 and is partly supported in a stirrup 23carried by the aforementioned braces or cross bars l4. The sectionalbands 24 surrounding the upper part of the motor cushioning bands andattached to the rods [4 function as suitable clamping means. Thus, themotor is cradled in rubber and because of this the machine may be saidto be equipped with floating power. A suitably bladed fan 25 is in thefan housing between the side walls and in alignment with the openings l9and 20. It will be noticed that the fan shaft has no direct metalcontact with the housing, and therefore there is no vibration or noiseat this vital point.

The upper section 26 of the standard is telescopically connected to therigid lower section l8. At its upper end it is provided with a gooseneck21 to which the hood or shell 28 is pivotally connected as at 29. As theupper section is raised to a predetermined elevation it is necessary totilt the hood down to obtain the desired angularity in relation to thehead of the patient (not shown). The tilting and adjusting means isshown in Figure 8. We provide two T-shaped members. One is fixed as at30' and the T-head 3| thereof provides a handle to*facilitate pullingand pushing the entire machine from place to place. The stem of thisrigid T- shaped member 30 is tubular to accommodate the rigid stem 32 ofthe other companion T- shaped member. The stem 32is provided withlongitudinally spaced notches forming keeper seats to accommodate thespring fingers or detents 33. The head portion of the movable T- shapedmember as indicated at 34, is pivotally connected at the point 35 to thehood. Thus the hood can be lifted up and down with the hand and thespring catch means will function automatically to hold it in anysuitable adjusted position. We want to emphasize in this connection theexisting expansible sponge rubber cushion 36 between the hood and theupright portion of the section 26'. By resting the bulk of the weight ofthe hood'on the cushion and connecting the cushion both to the standardand the hood, the hood is cushioned against vibration and noiseconstantly. This is an important advantage.

The hood is more or less of conventionalshape so far asits'ext'ernal'appearance is concerned.

It is% to be observed however, that it has special built-inconveniences; There-is an air'defiector lip 3 at the back. Then, theperimeter of the mouth is" provided with a part-segmental channel-38-with vents at the point 39'. This means 38' and 39 provides a shieldin the nature of a gutter to ,trap the'hot air current and to keep thesame from: direct contact with the forehead and sides of the ones face.On diametrically opposite sides the inboard wall or flangeof'gut'terlikeshield has arching risers of appropriate shape and dimension as at 40 inFigure 2. These form ear-guards, and it" will be noted that theregistering portions of the shell of the hood are provided withapertures having air intake screens 41. By equipping the hood with theseadditional safeguarding and comforting facilities, this part of thestructure isconsidered to be of outstanding importance.

Any suitable electric heating means may be provided on theconduitforming sectional standard. The means are generally referred to by thnumeral 42 in Figure 2. As shown in the diagram in Figure 7, two or moreindependent controllable coils or units may be employed, the switchmeans 43 being constructed to selectively control the intensity of theheat. We are not particularly concerned with this phase of the inventionand have shown broadly a diagram merely to illustrate the heat control.We are however, concerned with other additional details illustrated.That is to" say,

novelty is thought to reside in the laminated construction of thestandard sections as well as the hood. Each of these parts comprises anouter metal wall 44 and an inner metal lining or wall 45, there beingintervening asbestos or equivalent packing 46 whereby to insulate theserespective parts. That is, they are insulated against loss of heat andalso rendered somewhat vibrationless and sound-proof. To add to thestability and to minimize the vibration, the adjusting means for thetelescoping sections of the standard is preferably as detailed in Figure9. Here 4! designates a support for a tube 48 receiving a telescopingrod 49 connected to the movable standard'section-as indicated at 50. Aset screw 5| serves to interconnect the respective parts and tofacilitate raising and lowering of the hood carrying section of thestandard.

It' is thought that the description taken in connection with thedrawings will enable a clear understanding of the invention to be had.Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may be resorted to if desired.
